Looking for a 70cm DATV amplifier, for 437MHz.
Thank you.

Pallet to build up or a turn-key solution?

Jim G7NTG has some 300w pallets at a reasonable price, just bought two myself.

Hi all..

I do not mind if its a pallet or ready build tbh.

I did try emailing Jim but no response, maybe I have an old email address that he no longer uses.

Thanks
Matt

Hi Matt

It depends what you want in power terms. There are several options, from Aliexpress to a pallet you might need to modify. Jim imported several of the PAs you may have seen me talking about, they are good for 100W of DATV, and a lot more SSB/CW. Mods are in CQTV 286.

I have tried to email you but I don't know if your QRZ email is up to date. Jim's is OK in QRZ as far as I can tell.

Thanks Mike!

I received your email, thank you. And yep, I resent my email to his QRZ email address so hopefully get a reply.

To be honest, I just need enough power to reach GB3TV 437 input from here. I have tried a couple of these Chinese 25 watt amps, but they distort the signal if I push them too hard, i.e massive shoulders!

Although, if I had more power than needed, I could always experiment with others on 437.

Hopefully Jim will reply and I will see what he has available and if its cost effective for my needs.

Cheers

Matt

Hang on - so the GB3TV 70cm input is working now? I will have to try.

Apparently so. I have had zero success on 437 so far. However, G4IYT tested it yesterday from Leighton Buzzard and he was able to get in on 20 watts.

Mike, Just spoke to someone and they told me there will be a new 70cm lna and filter added soon. Apparently its currently extremely deaf on 70cm.

To confirm, I am now sorted for an amplifier thanks to Jim.

Thank you everyone that commented and advised.
